Transient Myasthenia Gravis (TMG) in newborns is characterised by low muscle tone, generalised muscle weakness, difficulties in sucking or swallowing, a weak cry, breathing difficulties and reduced physical activity.1,2
TMG is caused by the transfer of maternal antibodies through the placenta to the unborn child during pregnancy.1 TMG usually appears within 24 hours of birth and can last for 1-4 weeks before disappearing completely.1,2
Around 1 in every 10 newborn babies born to women with gMG may be at risk of TMG and need access to high-dependency support.1
